Abstract
The title compound, C34H52O4, consists of five six-membered rings. Barring the two rings, with double bonds, all other rings are in chair conformation s. Mean-plane and ring-puckering calculations indicate these two rings to b e in distorted-chair conformations, with distortion towards the boat confor mation. There are no strong hydrogen bonds and the structure is stabilized by van der Waals interactions only. The structure is compared with those re ported for other triterpenes.
